"In nonreciprocally violent relationships, women were the perpetrators in more than 70% of the cases."

""Overall, 24% of individuals assaulted by a partner at least once in their lifetime (23% for females and 19.3% for males)"

"Higher victimization for male than female high school students"

"Across studies, 40% of women and 32% of men reported expressive abuse; 41% of women and 43% of men reported coercive abuse"

"13.8% of the unidirectional violence was male to female (MFPV), 28.3% was female to male (FMPV)"

"None of the studies reported that anger/retaliation was significantly more of a motive for men than women’s violence; instead, two papers indicated that anger was more likely to be a motive for women’s violence as compared to men."

Differences in Frequency of Violence and Reported Injury Between Relationships With Reciprocal and Nonreciprocal Intimate Partner Violence: "Results. Almost 24% of all relationships had some violence, and half (49.7%) of those were reciprocally violent. In nonreciprocally violent relationships, women were the perpetrators in more than 70% of the cases. Reciprocity was associated with more frequent violence among women (adjusted odds ratio [AOR]=2.3; 95% confidence interval [CI]=1.9, 2.8), but not men (AOR=1.26; 95% CI=0.9, 1.7). Regarding injury, men were more likely to inflict injury than were women (AOR=1.3; 95% CI=1.1, 1.5), and reciprocal intimate partner violence was associated with greater injury than was nonreciprocal intimate partner violence regardless of the gender of the perpetrator (AOR=4.4; 95% CI=3.6, 5.5). Conclusions. The context of the violence (reciprocal vs nonreciprocal) is a strong predictor of reported injury. Prevention approaches that address the escalation of partner violence may be needed to address reciprocal violence."
